Dear R package developers: I need help on getting a package compiled for windows. I am trying to use definitions and routines from a set of libraries in that are in LINUX under #include <netdb.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h>
but these are unavailable in windows. I found that we can get these by including, in windows these includes: #include <winsock2.h> #include <io.h> My problem is I do not know how to instruct the preprocessor to include the linux .h files when in linux and the windows one in windows. I thought I found a solution online by using: #if defined(Win32) #include <winsock2.h> #include <io.h> #else #ifdef HAVE_UNISTD_H #include <unistd.h> #endif #ifdef HAVE_BSD_NETWORKING #include <netdb.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #endif #endif But I still get an error when these are compiled on the R-distribution. I do not understand where I am supposed to set the Win32 flag so that it will be ignored in LINUX but used in windows. where is "Win32" "HAVE_UNISTD_H" and "HAVE_BSD_NETWORKING" set? It seems that Makevars.win would be logical place, but I do not see how to do this. Thanks for any help.
